• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Michal Kurgan (RETIRED) 2005-06-02 11:35:58 UTC]

Until recent upgrade i could make my own qmake spec file dll's. But now i can  
compile dll's but when i want run app linked with created dll i ends with  
failed initialization. I triad also compile qwt-4.2.0, qwtplot3d-0.2.4 with  
same results. On older release everything works fine...  

Reproducible: Always
Steps to Reproduce:
1.emerge xmingw packages 
2.build dll with qmake 
3. 
 
Actual Results:  
failed initialization on run of application linked with dll 

Expected Results:  
working dll

I have added mingw-gcc-3.4.4 to portage.
If that does not fix it could you please provide more details how to repeat
the error or some files to play with.
( I do not use xmingw stuff for complex stuff )

after some more test i must say that it must be sth with qt.   
i succesfully build a simple and more complicated dlls, but problem with  
qwtplot3d persists, it just hungs... (program compiled natively on windows  
works ok, with all native compiled libraries like qt, qwt, qwtplot3d).  
  
What i found, it was that qt by default use -Wl,-subsystem,conole|windows for  
building dll's. It was main problem, it worked with older release, also it 
works on native windows, quite strange i would say...  
  
for me it's rather problem with crosscompilation of qt not a xmingw and i  
propose to invalidate bug or sth like that.

it's problem with some qmake cross-compilation settings
